Haha yea that's why I'm afraid to do it, my FW costs me enough as is because I got addicted to the hobby and have 4 tanks running now. I love SW fish and inverts so I'd have at least 4 SW. I'd put myself into so much debt lol

Also a 20 long breeding pair of leaf fish wont be to far off in the future!

over the years between coral , tanks , rock , fish , lights , well you get the idea
I have at-least 50k invested both fresh and salt
selling used equipment don't get you but peanuts these days lol
so I know the empty pocket feeling
and it just keeps going you just keep upgrading I just got a 90g
I give it a year I'll do it all over again but this time a 250g till the floor lets go lol

At the time of taking the picture it was just my 3 Boesemani Rainbow and 8 Rummy Nose Tetra, I've since added 4 Albino Cory's and 2 Assassin snails, next on the list is another 3 Boesemani. Considering BN pleco too but I think I will wait a while and do my substrate change before that.

Here's my newest 90g tank been up about a week
the build /transformation link is below in my signature if you want to see more
I tried my best to keep the lay out as close as my 40 was .
since that was my favorite and it wasn't a easy thing to recreate just needs some macro's now
